Definitions
- the invention relates to access of servers to Wireless Application Protocol (WAP) bearer systems.
- WAP Wireless Application Protocol
- the invention is directed towards providing a bearer interface layer to address these problems.
- an interface layer for a wireless server hosting server applications comprising:
- a uniform interface to the wireless server a bearer module interface for binding bearer modules to provide access of the server applications to bearer systems, and
- the functions comprises a configuration manager comprising means for maintaining configuration data relating to bearer modules and for responding to server application calls for a configuration list.
- the configuration manager comprises means for returning information regarding network type, bearer system type, and address type to server applications.
- the configuration manager comprises means for capturing bearer module information configured by a bearer developer within constraints of interfacing to the bearer module interface.
- the configuration manager comprises means for maintaining a configuration file for every bound bearer module.
- the functions include a bearer manager comprising means for registering bearer modules and for providing bearer module status information to requesting server applications.
- the bearer manager comprises means for responding to server application calls to register a bearer module. In one embodiment, the bearer manager comprises means for making a bind attempt to bind a bearer module to a transport mechanism.
- the bearer manager comprises means for responding to application calls to disconnect from a bearer module.
- the functions include a blacklist and whitelist manager comprising means for automatically testing all non-secure traffic.
- the blacklist and whitelist manager comprises means for filtering traffic according to parameters set by a server application.
- the functions include a callback handler comprising means for allowing a server application to call routines for pre-processing and post-processing of WDP packets.
- the functions include a log function comprising means for logging test data from a bearer module under test, and for providing said data to a requesting server application.
- the functions include a billing function comprising means for generating billing data on the basis of criteria supplied by a server application.
- the invention provides a wireless application server comprising WSP and WTP layers over an interface layer as defined above.
- Fig. 1 is an overview diagram showing the context of an interface layer of the invention
- Fig. 2 is a diagram showing the structure of the interface layer
- Figs. 3 and 4 are diagrams illustrating uses of the interface layer.
- Fig. 5 is a diagram illustrating signal interactions.
- interface layers 1 allow access by wireless servers 2 to bearer systems 3.
- the servers 2 include:-
- a WAP server 5 hosting prototype application and content
- a WAP proxy 6 performing protocol conversion and content encoding
- a WTA server 7 hosting telephony based applications.
- the servers are connected to a Web server 8 via a Firewall 9.
- the bearer systems are in this embodiment:-
- each interface layer 1 comprises a server interface 10 to the applications and WTP (Wireless Transaction Protocol) layer of the server.
- the interface 10 is uniform in its interfacing operations to all of the server applications. It also comprises an interface 11 to bearer system interfacing modules 20, called “bearers” or “bearer modules” in this specification. Between these two interfaces there is:
- a bearer manager 12 a configuration manager 13 , a log 14, a callback handler 15, a blacklist/ whitelist manager 16, a billing and CDR function 17, and an error function 18.
- the interface 10 is a uniform interface to all of the server applications and the interface 11 allows bearers 20 to be loaded and offers their services to the applications.
- one of the bearers 20 is a test bearer which writes to the log 14 and the log 14 returns responses to an application 25 on a WAP stack 26.
- This is a convenient framework for creation of new bearer modules 20. It also serves to examine and explain the facilities offered by an existing bearer 20. It is thus very suitable for testing bearer modules 20 and allows short development times.
- a WAP gateway 40 having a WAP stack 41 uses the interface layer 1 to access a data gateway 42 and an SMSC 43.
- Each of these bearer systems is accessed via a bearer module 20 (Bearer A and Bearer B).
- the gateway 42 is also accessed by a private interface 44 to be kept secret, while the SMSC is accessed via SMPP 45 (which is public).
- SMPP 45 which is public.
- the layer 1 allows versatility in the manner in which bearer developers may link their bearer system with a server: a private or a public protocol may be used.
- All of the bearer modules 20 are bound by the rules of the interface 11, but may or may not be private on the bearer system side. This is illustrated in Fig. 4 in which there is a secret interface 46 and an SMPP interface 47 on the bearer system side. The following describes the functions between the interfaces 10 and 1 1 in more detail.
- the manager 13 maintains a file which specifies which bearer modules are present, and there is a configuration file of bearer module parameters for each bearer module.
- Each bearer module consists of one or more bearer files and bearer configuration files. Where possible, bearer modules are designed for dynamic loading but where this is not possible or not desirable static linking of bearer modules is supported.
- the bearer manager 12 is responsible for the loading and management of the bearer modules. It performs version checking and license checking
- the contents of the lists are URLs or originator addresses.
- Fig. 5 Some of the above calls are illustrated in Fig. 5, in which server applications communicate with an SMSC bearer system for bi-directional transfer of WAP content. The following describes the calls in more detail, with examples of code.
- w c_bearer_list Returns the list of bearer modules configured by the system. The call actually returns the value of the bearer list parameter from the wdc-dtk.ini (layer 1 configuration file). Each item in the bearer list is known as a bearer tag and can be used to retrieve information on that bearer using the "wdc_info" call.
- the information returned includes the information from the "Network Bearer table" defined by WAP.
- a connection is not required to obtain information about the bearer.
- a handler for each of the above calls is provided. How the call is implemented is decided by the developer of each bearer module within the constraints imposed by the interface 11. For example a developer can chose to implement the "wdc_parm" handler to read from a flat file, to read from a database or to permanently return a blank value.
- This function is used by the application to connect to a bearer. It makes an application layer connection to the bearer.
- the bearer module should, on a 'bind', attempt to connect/bind to the transport mechanism to ensure it is in place. If an application wants to connect to multiple bearer systems, say USSD and SMS, then it must make multiple bind calls:
- This function returns a non-NULL connection identified which will be used by all further call to this bearer until the connection is terminated.
- the function returns null and stores an error in the global error number variable.
- wdc close This tells the bearer module that the server application is disconnecting. All resources allocated to using the bearer should be freed.
- one of the areas the layer 1 simplifies is the complex area of interfacing to telecom billing and prepaid systems. It is possible for an application to instruct the layer 1 to load and enable a billing sub module. The application may chose to enable the layer 1 to automatically log location URL and/or Volume of data as CRD for billing. This is only possible for WAP if the non- secure port is used.
- the INI setting "billing_module" points to the location of the billing module to load.
- the application may call the layer 1 to create CDRs.
- the INI parameter is the INI parameter
- Black_while_list indicates the file to use.
- This call is used to get a value of a configuration parameter from one of the configuration files.
- the wdcjmodule parameter selects which of the module - MAIN or one of the bearers is queried. Having a separate configuration file for each bearer module is necessary to prevent naming conflicts when bearer modules are provided by third parties.
- Callbacks are provided by the layer 1 to allow an application request that it handles various events:
- ERROR - allows the application register its own handler for error conditions this is useful it the application already has an error logging facility that it wishes to use.
- LOG - allow an application to register its own handler for logging messages.
- the interface layer 1 also allows the addition of new bearers as they become available, and the application to utilise 'intelligent' selection of bearers.
